Viega 84770 – Frequently Asked Questions
1) Is the Viega 84770 the right way to take a 3/4 inch branch off a 1-1/4 inch steel line?
Yes, if you want that branch threaded. The 84770 presses onto the 1-1/4 inch carbon steel run and gives you a 3/4 inch female thread for a drop, a valve, or a gauge. If you want the branch pressed instead of threaded, use a reducing MegaPress tee with press outlets rather than this adapter.
2) Can I use the Viega 84770 MegaPress fitting on copper or PEX?
No. The 84770 is carbon steel and is a MegaPress fitting, which presses onto black iron or carbon steel pipe. Copper tube takes a ProPress copper fitting and PEX takes a PureFlow fitting; neither works with this press profile or material.
3) What does Viega Smart Connect do on the 84770?
Smart Connect is a deliberate leak path built into the fitting: before pressing, an unpressed connection will visibly weep under test pressure so the installer can find it and press it. It does not replace pressure testing, but it keeps an un-pressed joint from being buried behind finish work.
4) Does the Viega 84770 come with the press jaw or sealing element?
The sealing element is factory installed inside the press end; the press tool and the 1-1/4 inch MegaPress jaw are separate and are not supplied with the fitting. Order the jaw to match the 1-1/4 inch press size if you do not already have it on the truck.
